The current study aims to do rainfall analysis of Jhunjhunu district with reference to time and space for a period of 22 years by using quantum geographic information system (qGIS). The data collected were yearly rainfall and rainy days. These data were analysed in qGIS software. Inverse Distance Weighting (IDW) method of interpolation was adopted for the study. Thematic maps were generated. Rainfall maps displayed a growing tendency in rainfall amount while rainy days represented a slow increasing pattern. It was found that south, south-eastern and some part of north region of the Jhunjhunu get the utmost rainfall. However, north-eastern and western parts of the district receive the lowermost rainfall. It was observed that Khetri block received the highest rainfall during the average 20 years period. Though, Jhunjhunu block got the lowest rainfall during the whole period. Malsisar and Udaipurwati blocks got average rainfall. As ground water recharge rate is low in the study area, it is essential to collectively utilise surface water, available rainfall and groundwater for optimum irrigation and further agricultural management in the district. The rainfall analysis facilitated the understanding of the rainfall pattern which would be advantageous for strategic planning of efficient irrgiation and water availability in the study area.
